About Twin Lakes Tract
Twin Lakes Tract campground lies in the high Sierra along the Yosemite corridor, east of Highway 120 between Lee Vining and Yosemite National Park. The site occupies rolling forest and meadow at 8,606 feet, anchored by glacial lakes and granite backdrop. Access runs via Highway 120 from the west (Yosemite Valley, 90 minutes) or from the east (Lee Vining, 30 minutes). The campground operates as a staging point for backpackers, day hikers, and fishers targeting the Twin Lakes basin. Parking fills on weekends and holidays; arrive early or plan a weekday visit. Winter closure depends on Highway 120 snowpack; typical open season spans May through October, though shoulder-season access varies.
Spring and early summer bring frequent afternoon wind gusts to 31 mph as thermal gradients sharpen. The 30-day average wind of 12 mph masks the diurnal cycle: calm mornings shift to gusty afternoons by 2 p.m. Temperatures average 31 degrees in the rolling 30-day window but swing from lows near 16 degrees on clear nights to highs approaching 47 degrees by late afternoon. Crowding remains low relative to valley campgrounds (12.0 average on the rolling metric), peaking the first full weekend after Highway 120 reopens and again around midsummer. Snow lingers into June in most years; drifts block higher trails until July. By late September, afternoon winds ease and temperatures stabilize in the upper 30s.
Twin Lakes Tract suits backpackers staging multi-day Sierra traverses, day hikers targeting alpine lakes, and anglers working the Twin Lakes outlet. The campground handles vehicles and trailers on a first-come basis; no reservations. Experienced visitors plan morning departures or evening returns to avoid peak wind. The site's high elevation and exposure mean afternoon thermals are reliable; skip the afternoon if you're paddling or seeking stable conditions. Smoke from distant fires can degrade air quality by late summer. The campground has no cell service; navigation relies on maps.
Nearby alternatives include Convict Lake and Rock Creek Lake, both lower and somewhat more sheltered than Twin Lakes Tract. June Lake Loop offers similar elevation and access but sits deeper in a canyon, reducing afternoon wind exposure. The Yosemite corridor's main draw remains the park itself; Twin Lakes Tract functions best as a quieter satellite for those avoiding valley crowds or staging backpacking trips into the wilderness boundary.
